If "[*]" is given as the last part of a QOM property name, treat that as an array property. The added property is given the first available name, replacing the * with a decimal number counting from 0. First add with name "foo[*]" will be "foo[0]". Second "foo[1]" and so on. Callers may inspect the ObjectProperty * return value to see what number the added property was given.

2014-07-01qom: add a generic mechanism to resolve pathsPaolo Bonzini1-29/+53
It may be desirable to have custom link<> properties that do more than just store an object. Even the addition of a "check" function is not enough if setting the link has side effects or if a non-standard reference counting is preferrable. Avoid the assumption that the opaque field of a link<> is a LinkProperty struct, by adding a generic "resolve" callback to ObjectProperty. This fixes aliases of link properties.

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi1-1/+17
There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi1-3/+33
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

2013-12-24qom: Do not register interface "types" in the type table and fix namesPaolo Bonzini1-11/+21
There should be no need to look up nor enumerate the interface "types", whose "classes" are really just vtables. Just create the types and add them to the interface list of the parent type. Interfaces not registering their type anymore means that accessing superclass::interface by type name will fail when initializing subclass::interface. Thus, we need to pre-initialize the subclass's parent_type field before calling type_initialize. Apart from this, the interface "types" should never be used and thus it is harmless to leave them out of the hashtable. Further, the interface types had a bug with interfaces that are inherited from a superclass: The implementation type name was wrong (for example it was subclass::superclass::interface rather than just subclass::interface). This patch fixes this as well.

2013-12-24qom: Split out object and class cachesPeter Crosthwaite1-6/+7
The object-cast and class-cast caches cannot be shared because class caching is conditional on the target type not being an interface and object caching is unconditional. Leads to a bug when a class cast to an interface follows an object cast to the same interface type: FooObject = FOO(obj); FooClass = FOO_GET_CLASS(obj); Where TYPE_FOO is an interface. The first (object) cast will be successful and cache the casting result (i.e. TYPE_FOO will be cached). The second (class) cast will then check the shared cast cache and register a hit. The issue is, when a class cast hits in the cache it just returns a pointer cast of the input class (i.e. the concrete class). When casting to an interface, the cast itself must return the interface class, not the concrete class. The implementation of class cast caching already ensures that the returned cast result is only a pointer cast before caching. The object cast logic however does not have this check. Resolve by just splitting the object and class caches.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+1
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-09-20cpu: Move cpu state syncs up into cpu_dump_state()James Hogan1-0/+1
The x86 and ppc targets call cpu_synchronize_state() from their *_cpu_dump_state() callbacks to ensure that up to date state is dumped when KVM is enabled (for example when a KVM internal error occurs). Move this call up into the generic cpu_dump_state() function so that other KVM targets (namely MIPS) can take advantage of it. This requires kvm_cpu_synchronize_state() and cpu_synchronize_state() to be moved out of the #ifdef NEED_CPU_H in <sysemu/kvm.h> so that they're accessible to qom/cpu.c.

2013-09-03cpu: Replace qemu_for_each_cpu()Andreas Färber1-21/+9
It was introduced to loop over CPUs from target-independent code, but since commit 182735efaf956ccab50b6d74a4fed163e0f35660 target-independent CPUState is used. A loop can be considered more efficient than function calls in a loop, and CPU_FOREACH() hides implementation details just as well, so use that instead.

2013-08-30qom: Assert instance size in object_initialize_with_type()Andreas Färber1-3/+4
This catches objects initializing beyond allocated memory, e.g., when subtypes get extended with instance state of their own. Suggested-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andreas Färber <afaerber@suse.de>

To be passed on to object_initialize_with_type(). Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com> (virtio-ccw) Signed-off-by: Andreas Färber <afaerber@suse.de>
